I don't think libstdc++v3 is special about this, thus in the various .cc files there is nothing special, you can only find instantation files for templates, which end with -inst, normally, and definitions for everything else. Besides that, but this doesn't matter if you are interested in *sizes*, you also have to update the patterns in the linker script, to make sure that the new symbols are actually visible.
